Zo all whom it may concern:

Be it known'that I, ARTHUR JAMES BAZE- LEY, of Oleveland,'Cuyahogacounty, Ohio,

have invented a new and useful Car-Coupler,

of which the following is a full, clear, and ex -act description,reference being had to the accompanying drawings, forming part of thisspecification, in which-- Figure 1 shows two of my couplers coupledtogether, one of them being in plan and the other in horizontal section.Fig. 2 is a rear elevation, partlyin .vertical section, the couplerbeing, in locked position. Fig. 3 is a front elevation showing theknuckle-tail in vertical section and the device in lock-set position.Fig. 4 is a side elevation of Fi 1, partly broken away and showing thefool: locked. Fig. 5 is a longitudinal section showing the knuckle open.Fig. 6 is a rear elevation, partly in section, the knuckle being openandthe lever-18 raised to full 0 ening position; and Fi ,7 illustrates amodi cation is opening member.

a car-coupler of simple construction adapted without the necessity ofthe operator passing between the cars to lock and unlock the knuckle tothrow the knuckle open or to lofckset itthat is to say, to unlock it andto leave it in unlocked position, so that it will open when the couplerto which it is coupled is pulled away. Means are also provided by whichthe lock is locked and held positively from creeping upwardly. All thesefeatures are secured with simplicity of apparatus and with greaterefficiency than heretofore, and as these matters are of great moment incarcoupler constructions my invention is of importance and value.

and adapted'to fit beneath a shoulder on the draw-head for the purposeof holdingthe lock An opening-lever is the sliding opening member, movesit independently of the lock,

' so as to free it from beneath the shoulder in the draw-head, and thenraises the lock and pushes the opening member against the knuckle forthe purpose of moving the knuckle openQ attached by a on the interior ofthe c0upler-head,and has also the knuckle-tail a shoulder formed by arecess 7 for the purpose of supporting the lock in lockset position. ,Acoupler-knuckle thus formed with a hook for engaging a shoulder on adraw-head and having on the rear surface of its tail a shoulder forholding the lock in lockset position is new in itself, and I intend tomake special claim thereto.

The lock 8 is vertically movable and 1s set in a recess 9 in thecouplenhead. It 1s ca able of movin vertically in this recess an ofbeing rotate therein. To provide for 1ts rotation,the up er end of therecess is closedby a cap 9, who 1 is preferably removable, being rotarylocking device 10.

In the'operation of the lock it is first hfted so as to bring its upperend into contact with the cap and is then rotated, the rotat on belngfacilitated, preferably, by a projectlon 8 at the upper end of the lock,which serves as a vertical pivot and engages the under side of the cap,preferably in a curved recess thereon. The lock has a locking portion 11and below it a cut-away or recessed portion 12, so that when the lock isin its lowest position the lockin portion is opposite the ta1l of theknuck e and confines the same, and 1f-1t 1s raised the recessed portionwill be brought opposite to the knuckle-tail and Wlll leave it free tobe swung open. -At the lower end of the lock and mounted in an inclinedshdeway 13 thereof is an opening member 14, preferably of approximatelyU shape, one of 1ts arms fitting in the inclined slot 13, its mteron itsouter lateral face and below the top of mediate portion beingsubstantially horizon tal and its other arm having ashoulder 15, adaptedto take under a shoulder 16 1n the draw-head, and having ashoulder orproec tion 17, adapted to take into the recess 7 on the knuckle when inlock-setting position.

When the lock is in its locking position, the

member 14 fits in a vertical recess B in the ICC 45 thus causingits'inner end-toengage the memflo or of the coupler-head and is heldthereby from turning horizontally. It may also be held from turning bybeing formed with a squared portion b, which when the coupler is lockedfits against as uared'portion ofthe draw-head, Figs. 1 an 2, but whichwhen .the lock is raised comes opposite to a recess and will then opposeno obstacle to the turnin of the lock, Fig. 6.

pro

elow the member 14 18 an opening arm or lever 18, which is fulcrumed inthe-draw-head on a pin 19, inolined so that the lever will ,turn in aninclined plane having an upward and forward'dnectlon, the upperdirection being for the purpose of raising the lock by motion impartedprimarily to the opening member and the forward direction beingfor thepurpose of pushing the opening member -14 against-the knuckle, and thusthrowing the knuckle-open, the lock meanwhile rotating on its'verti oalaxis, so as tofaccommodate itself tothe; motion of the opening member.The lower jurface of the opening member 14 is Ibeveled, as shown, inorder thatit may present a surface approximately at right angles to theplane of motion of the opening-lever and may thus facilitate its action.

When the parts of the coupler are in locked position, the tail of theknuckle extends toward the rean of the coupler and the lock is in itslowest position, with the portion 11 thereof blocking the tail of theknuckle, and theopening member 14 also in its lowest pos1t1on,hav1ngmoved downwardlyin the inclined slot 13, its shoulder 15 fitting underthe shoulder 16 on the draw-head, Fig. 2. If

" aim the jarring motion of the car the lock should tend to rise, itcannot draw the member away from the shoulder 16, and the enagement ofthe member 14 with said shouli er will positively and effectively holdthe 'lockdown. in its locked position.

-.If it is-desired to unlock and lock-set the f coupler-without throwingthe knuckle open,

the operator moves the opening-lever 18,

' :ber 14 and to move it in the inclined slot 13,

thusreleasing its shoulder 15 from engagemerit with the shoulder 16 onthe draw-head, s until the lockin I the knuckle an' I as freed. thesame, and the and thenraising-it, together with. the lock 8, ortion-11has passed above member 14 is lifted above the limit of the slot ositeto the recess 7 onthe rear face of the uckle-tail, and thezopeningmember 14 being free to turn radially. the leverthen turns it on thevertical axis ofthe lock, bringing the-shoulder 17 'intothe recess 7,Fig. 3. This su-pportsthe member 14, and the lock in unlocked position,leavin the knuckle free to .be pulled .open when t e car to which it issilentwith-the. coupler of another car an it .o'oupled is drawn away. Ap I.

'I the knuckle is closed andnot int en'ga e- .is desired to 'swin 'B.This motion brings the shoulder 17 on- 'ituated by motion impartedprimaril the lock turns; substantially as described.

seem? it' into open position, the

operator moves t e lever 18 to its full ex- .tent, Figs. 5 and 6. Thisraises the-member 14 free of the recess B in the floor of the Acoupler-head, as above-explained,';a-nd then turns it radially on theaxis of the lock and pushes the knuckle into open position. When theknuckle is next moved back, it will push the member 14 before it untilsaid member comes above the recess B in the floor e he coupler-head,when the lock and u ning member will drop and thelock enga g the. frontof the knuckle-tail will hold it in locked position.

Within the scope of the invention as herein claimed the parts may bemodified in many ways. Thus thegpurpose of making the,

opening member 14 separate from the lock and fitting it movable theretois to enable the lock to be this function is not desired the openingmember 14 may be made integral with thelock and the shoulder 15dispensedwith.

locked in its locked position; but if .In Fig. 71 show anothermodificationin which the opening member 14 is connected by a pivotaljoint 20 with the lock 8 and thus affords the slight independent motionnecessary to cause the shoulder 15 to engagethe down-holding shoulder 16on the drawhead.

Other modifications may be made by those 4 skilled in the art.
